Benefits
Saves Time
Easy to Install and Simple to Operate
Does not require programming or commissioning
Up and running in less than 10 minutes.
Motors Last Longer
Proprietary CL Software
Provides overload protection, prevents motor burnout
and eliminates nuisance tripping.
UL approved as electronic overload protector for motors.
Energy Saving
Uses only the power the application requires
Energy savings is realized by using variable motor speed
vs. constant speed motors.
Economical to Use: Indoors or Out
Eliminates secondary enclosure
No holes to drill, no switches to install.
No need to derate drive for high starting torque applications.
Combines Soft Start with Variable Speed
Adjustable Soft Start.
KB Customization for OEM’s
“You get exactly what you need. Nothing more, Nothing less.”
Includes: custom label, preset calibration, installing drive options and custom software.
Ready to use out of the box.
GFCI software* allows equipment to operate with Ground Fault Circuit Interruption circuit breakers or outlets.
*With factory programming.

Additional Features
Sensorless Flux Vector Control
Flux Vector Compensation with Static Auto-Tune provides excellent speed regulation
with high torque loads throughout the entire speed range. Auto energy saving at light
loads. Smooth motor torque.
Electronic Inrush Current Limit (EICL™) Protection
Eliminates harmful inrush AC line current during power up.
Run/Fault Relay Output Contacts
Can be used to turn equipment on or off, to signal a warning if the drive is put into
“Stop” mode, or to signal if a fault has occurred
.
Start/Stop Switch
Provides electronic “Start” and “Stop” functions.
Ride-Through
Provides smooth recovery to the previous set speed during a momentary power loss.
Holding Torque at Zero Speed
Resists motor shaft rotation when the drive is in “Stop” mode.
Regeneration Protection
Eliminates tripping due to high bus voltage caused by rapid deceleration of high
inertial loads.
Undervoltage and Overvoltage Protection
Shuts down the drive if the AC line input voltage goes above or below
the operating range.
Short Circuit Protection
Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).
Basic, Programmable, Trimpot Adjustments
Min. Speed, Max. Speed, Accel, Decel, Current Limit, Slip Comp.
Drive Options
On/Off AC Line Switch
Disconnects the AC line.
Forward-Stop-Reverse Switch
Provides motor reversing and stop functions.
Signal Isolator
Provides isolation between a non-isolated signal source and the drive.
Auto/Manual Switch
When used with the Signal Isolator, it selects the remote process signal
or the Main Speed Potentiometer.
Class “A” (CE) RFI Filter
Installs inside the drive.
Liquidtight Fittings
Provides a liquid-tight seal for wiring the drive. Kit includes necessary
liquid-tight ttings.
